Elaborate petals and staminodes in eudicots: Diversity, function, and evolution [PDF]

open access: yesOrganisms Diversity and Evolution, 2006
Petals, a characteristic feature of eudicots, have evolved elaborations in various ways and across diverse clades. In this survey of petal and staminode elaborations throughout the eudicots, based on both new studies and a review of the literature, the ...
